Core Descriptor Sets for Rectal Prolapse Outcomes Research Using a Modified Delphi Consensus.

BACKGROUND: There is wide variation in prolapse care. OBJECTIVE: To determine core descriptor sets for rectal prolapse to enhance outcomes research. DESIGN: Descriptors for patients undergoing rectal prolapse surgery were generated through a systematic review and expert opinion. Stakeholders were recruited internationally via listserv and social media. Experts were encouraged to consider the minimum descriptors that could be considered during clinical care, and descriptors were grouped into core descriptor sets. Consensus was defined as greater than 70% agreement. SETTING: A 3-round Delphi process using a 9-point Likert scale based on expert results was distributed via survey. The final interactive meeting used a polling platform. PARTICIPANTS: The Pelvic Floor Disorders Consortium interdisciplinary group convened to advance the clinical care of pelvic floor disorders. MAIN OUTCOME MEASURES: To achieve expert consensus for core descriptor sets for rectal prolapse using a modified Delphi method. RESULTS: A total of 206 providers participated, with survey response rates of 82% and 88%, respectively. Responders were from North America (56%), Europe (29%), and Latin America, Asia, Australia, New Zealand, and Africa (15%). Ninety-one percent of participants identified as colorectal surgeons and 80% reported >5 years of experience (35% reported >15 years). Fifty-seven attendees participated in the final meeting and voted on core descriptor sets. Ninety-three percent of participants agreed that descriptors such as age, BMI, frailty, nutrition, and the American Society of Anesthesiology score correlated to physiologic status. One hundred percent of participants agreed to include baseline bowel function. One hundred percent of participants reported willingness to complete a synoptic operative report. Follow-up intervals 1, 3, and 5 years after surgery (76%) with a collection of recurrence and functional outcomes at those time periods reached an agreement. LIMITATIONS: Individual bias, self-identification of experts, and paucity of knowledge related to rectal prolapse. CONCLUSIONS: This represents the first steps toward international consensus to unify language and data collection processes for rectal prolapse. See Video Abstract .

The SAGES MASTERS program presents: the top 10 seminal articles for laparoscopic left and sigmoid colectomy pathway for uncomplicated disease.

BACKGROUND: As one of the 8 Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program clinical pathways, the Colorectal Pathway aims to deliver educational content for the general surgeon organized along 3 levels of performance (competency, proficiency and mastery) each represented by an anchoring procedure. In this article, the SAGES Colorectal Task Force presents focused summaries of the top 10 seminal articles selected for laparoscopic left/sigmoid colectomy for uncomplicated disease. METHODS: Using a systematic literature search of Web of Science, the most cited articles on laparoscopic left and sigmoid colectomy were identified, reviewed, and ranked by members of the SAGES Colorectal Task Force. Additional articles not identified in the literature search were included if deemed impactful by expert consensus. The top 10 ranked articles were then summarized, including their findings, strengths and limitations with emphasis on relevance and impact in the field. RESULTS: The top 10 articles selected focus on variations in minimally invasive surgical techniques, video demonstrations, stratified approaches for benign and malignant disease as well as assessments of the learning curve. CONCLUSIONS: The selected top 10 seminal articles for laparoscopic left and sigmoid colectomy in uncomplicated disease are considered by the SAGES colorectal task force to be fundamental to the knowledge base of minimally invasive surgeons as they progress to mastery in these procedures.

Disparities in Characteristics, Access to Care, and Oncologic Outcomes in Young-Onset Colorectal Cancer at a Safety-Net Hospital.

PURPOSE: Young-onset colorectal cancer is an emerging cause of significant morbidity and mortality globally. Despite this, limited data exist regarding clinical characteristics and outcomes, particularly in safety-net populations where access to care is limited. We aimed to study disparities in clinical characteristics and outcomes in patients with young-onset colorectal cancer in the safety-net setting. METHODS: We performed a retrospective review of patients < 50 years old diagnosed and/or treated for colorectal cancer between 2001 and 2017 at a safety-net hospital. Kaplan-Meier and Cox regression models were constructed to compare overall survival (OS), progression-free survival (PFS), and relapse-free survival (RFS) by race and ethnicity, stratifying for relevant clinical and pathologic factors. RESULTS: A total of 395 young-onset patients diagnosed at a safety-net hospital were identified and 270 were included in the analysis (49.6% Hispanic, 25.9% non-Hispanic Black, 20.0% non-Hispanic White, and 4.4% other). Non-Hispanic White race was independently associated with worse OS (hazzard ratio [HR], 0.53; 95% CI, 0.29 to 0.97), as were lack of insurance, higher clinical stage, and mismatch repair proficiency. There was no significant difference seen in PFS or RFS between racial and ethnic groups. CONCLUSION: Non-Hispanic White race or ethnicity was found to be independently associated with worse OS in a safety-net population of patients with young-onset colorectal cancer. Other independent predictors of worse OS include higher stage, lack of insurance, and mismatch repair proficiency.

Vaginal cuff perforation during robotic-assisted mesh recto-sacrocolpopexy.

INTRODUCTION: We report on the management of intraoperative vaginal cuff perforation during robotic-assisted mesh recto-sacrocolpopexy for vaginal vault prolapse with defecatory dysfunction. CASE PRESENTATION: A 75-year-old woman with vaginal bulge and constipation was to undergo a joint robotic mesh recto-sacrocolpopexy. Intraoperatively, mesh was secured to the left posterior vaginal wall following dissection. Prior to contralateral suture placement, the vaginal cuff split open and exposed an end-to-end anastomotic sizer previously inserted in the vagina. Due to subsequent mesh erosion risk, we proceeded with vaginotomy closure with running and interrupted absorbable sutures, removal of mesh, direct suture rectopexy to the promontory, and enterocele defect correction by reapproximating the right and left wings of the peritoneum flaps over the rectum with running sutures. Patient reported satisfactory outcomes after 2 years. CONCLUSION: We reviewed our experience with vaginal cuff perforation during robotic-assisted mesh recto-sacrocolpopexy prompting enterocele repair and rectopexy without mesh.

Feasibility and Outcome of Routine Use of Concurrent Chemoradiation in HIV-positive Patients With Squamous Cell Anal Cancer.

OBJECTIVES: Clinical concerns about hematologic toxicities in human immunodeficiency virus (HIV)+ patients with squamous cell anal cancer (SCAC) may lead to de-escalation of treatment intensity. The objective of this study is to evaluate clinical outcomes including toxicity following standard concurrent curative-intent chemoradiation for HIV+ and HIV- patients with SCAC. MATERIALS AND METHODS: Among 97 evaluable patients treated between 2009 and 2016 (median age 52.2 y), 43 (44.3%) were HIV+ and 54 (55.7%) HIV-. The majority of the radiation was delivered using intensity-modulated radiation therapy and chemotherapy consisting primarily (93%) of 5-fluorouracil and mitomycin C. Clinical outcomes assessed included toxicity, locoregional control (LRC), distant metastasis (DM), progression-free survival (PFS), colostomy-free survival (CFS), overall survival (OS), and cause-specific survival (CSS). RESULTS: With a median follow-up of 45 months, HIV+ patients exhibited a trend toward reduced OS compared with HIV- patients (4 y OS 61.2% vs. 78.3%; HR 2.09; 95% CI, 0.97-4.52; P=0.055) on univariable analysis, but HIV status was not significant after adjusting for additional parameters on multivariable analysis. Toxicity rates, LRC, CFS, PFS, freedom from DM, and CSS were similar between the 2 cohorts. On multivariable analysis, tumor size >5 cm impacted all clinical outcomes (trend for LRC) except CFS. Radiation treatment extension beyond 7 days was found to negatively impact LRC and CSS. Male sex was associated with worse CFS. CONCLUSIONS: Radiation therapy with concurrent 5-fluorouracil and mitomycin C chemotherapy is reasonably well-tolerated as curative treatment for HIV+ patients with SCAC, and no significant difference in outcomes was noted relative to HIV- patients.

Current Status of the Management of Stage I Rectal Cancer.

PURPOSE OF REVIEW: To summarize the current available treatments for stage I rectal cancer and the evidence that supports them. RECENT FINDINGS: Radical surgery, or total mesorectal excision (TME) without neoadjuvant therapy, reports excellent oncologic outcomes, with 5-year disease-free survival of approximately 95%. Alternative therapies include local excision, which has acceptable long-term outcomes in some low-risk T1 tumors; but overall local excision, with or without additional chemotherapy or radiation, generally reports 5-year disease-free survival less than TME alone. New research is showing complete clinical response rates of 67% with chemoradiation combined with additional consolidation chemotherapy in T2 lesions, making watch and wait a potential strategy for stage I tumors. Owing to its superior oncologic outcomes, radical surgery remains the mainstay of treatment for stage I tumors. Both local excision and watch and wait have advantages that may make them useful in individual patients and should be considered under the right circumstances.

Modified Transanosphincteric (York Mason) Repair of Nonradiated Rectourinary Fistulae: Patient-reported Fecal Continence Outcomes.

OBJECTIVE: To review our experience with the modified York Mason (MYM) procedure in the treatment of rectourinary fistulas (RUFs) and to assess fecal continence using patient-reported measures. MATERIALS AND METHODS: A retrospective review was performed of patients who underwent MYM repair of nonradiated RUF with gluteal free fat graft from 2008 to 2016 at a single institution. Success was defined as resolution of the fistula without need for further surgery. The Cleveland Clinic-Florida Wexner Fecal Incontinence Score (CCFFIS) and the Patient Global Impression of Improvement (PGI-I) surveys were administered by phone. RESULTS: Of 17 patients who underwent MYM repair with a mean age of 61.8 years old, the most common fistula etiologies were prostatectomy in 11 patients (65%), cryoablation in 2 patients (12%), and transanal tumor excision (12%). Three patients (18%) failed prior perineal repairs. The mean fistula size was 10.1 mm (range 2-25), the median operative time was 231 minutes (range 151-365), and the median length of stay was 2.0 days (range 1-13). At the median follow-up of 39.4 months, 16 of the 17 patients (94%) had successful primary closures. The condition of the 10 patients who responded to the phone survey was "much better" (median PGI-I score 2), with 89.5% mean improvement. The mean CCFFIS was 1.4 (range 0-5) on a scale of 0 (total continence) to 20 (complete incontinence). Two patients (20%) reported rare (<1 per month) fecal incontinence, and 2/10 (20%) reported frequent flatal incontinence, but none reported significant lifestyle change or sought further treatment for bowel symptoms. CONCLUSION: The MYM technique has a high success rate in the treatment of nonradiated RUF with negligible impact on fecal continence.

Colo-colonic anastomosis in a continuous-flow left ventricular assist device patient.

Noncardiac operations are being increasingly performed on patients with left ventricular assist devices (LVADs). However, little is known on the impact of continuous-flow LVADs on the vascular supply of the colon for anastomoses. In this case, a 67-year-old male supported on an LVAD underwent four successful noncardiac operations including two intestinal anastomoses; left colon and small bowel anastomosis. To the best of our knowledge, no existing literature has reported successful colonic anastomosis on a continuous-flow LVAD. This case illustrates the plausibility of performing colonic anastomoses with appropriately selected patients supported on an LVAD. A 67-year-old male with congestive heart failure underwent LVAD placement for decompensated heart failure while awaiting orthotopic transplantation. During his recovery, he developed a stage IV sacral decubitus ulcer which required a sigmoid loop colostomy placement and a rotational flap. Subsequent stoma closure with partial sigmoid colectomy and stapled anastomosis was performed, and healed without evidence of anastomotic leak. This case illustrates the potential for colonic anastomoses for patients on continuous-flow LVAD support. Although oxygenation is known to be an important aspect of healing, this patient's outcome suggests that intestinal anastomoses can be performed on the induced pulseless environment of an LVAD. Further studies will be needed to further elucidate the success of longer segment resections and appropriate surgical candidates.

Premium copayments and the trade-off between wages and employer-provided health insurance.

This paper estimates the trade-off between salary and health insurance costs using data on Illinois school teachers between 1991 and 2008 that allow us to address several common empirical challenges in this literature. Teachers paid about 17 percent of the cost of individual health insurance and about 46 percent of the cost of their family members' plans through premium contributions, but we find no evidence that teachers' salaries respond to changes in insurance costs. Consistent with a higher willingness to pay for insurance, we find that premium contributions are higher in districts that employ a higher-tenured workforce. We find no evidence that school districts respond to higher health insurance costs by reducing the number of teachers.

Diagnostic testing for fecal incontinence.

Many tests are available to assist in the diagnosis and management of fecal incontinence. Imaging studies such as endoanal ultrasonography and defecography provide an anatomic and functional picture of the anal canal which can be useful, especially in the setting of planned sphincter repair. Physiologic tests including anal manometry and anal acoustic reflexometry provide objective data regarding functional values of the anal canal. The value of this information is of some debate; however, as we learn more about these methods, they may prove useful in the future. Finally, nerve studies, such as pudendal motor nerve terminal latency, evaluate the function of the innervation of the anal canal. This has been shown to have significant prognostic value and can help guide clinical decision making. Significant advances have also happened in the field, with the relatively recent advent of magnetic resonance defecography and high-resolution anal manometry, which provide even greater objective anatomic and physiologic information about the anal canal and its function.

Single-site laparoscopic surgery for inflammatory bowel disease.

BACKGROUND AND OBJECTIVES: Single-site laparoscopic colorectal surgery has been firmly established; however, few reports addressing this technique in the inflammatory bowel disease population exist. METHODS: We conducted a case-matched retrospective review of 20 patients who underwent single-site laparoscopic procedures for inflammatory bowel disease compared with 20 matched patients undergoing multiport laparoscopic procedures. Data regarding these patients were tabulated in the following categories: demographic characteristics, operative parameters, and perioperative outcomes. RESULTS: A wide range of cases were completed: 9 ileocolic resections, 7 cases of proctocolectomy with end ileostomy or ileal pouch anal anastomosis, 2 cases of proctectomy with ileal pouch anal anastomosis, and 2 total abdominal colectomies with end ileostomy were all matched to equivalent multiport laparoscopic cases. No single-incision cases were converted to multiport laparoscopy, and 2 single-incision cases (10%) were converted to an open approach. For single-incision cases, the mean length of stay was 7.7 days, the mean time to oral intake was 3.3 days, and the mean period of intravenous analgesic use was 5.0 days. There were no statistically significant differences between single-site and multiport cases. CONCLUSIONS: Single-site laparoscopic surgery is technically feasible in inflammatory bowel disease. The length of stay and period of intravenous analgesic use (in days) appear to be higher than those in comparable series examining outcomes of single-site laparoscopic colorectal surgery, and the outcomes are comparable with those of multiport laparoscopy. This may be because of the nature of inflammatory bowel disease, limiting the benefits of a single-site approach in this population.

Incisional negative pressure wound therapy significantly reduces surgical site infection in open colorectal surgery.

BACKGROUND: Surgical site infections in colorectal surgery remain a common problem, and are associated with an increase in cost of care and length of stay. OBJECTIVE: This study aims to evaluate the effect of known risk factors and the use of incisional negative pressure wound therapy on surgical site infection rates. DESIGN: This is a single-center retrospective study with the use of chart review. SETTINGS: The study took place at a tertiary academic medical center. PATIENTS: All patients undergoing open colectomy at a single institution from 2009 through 2011 were studied. MAIN OUTCOME MEASURES: The primary outcome measured was the presence or absence of surgical site infection. RESULTS: Overall, 69 of the 254 patients (27.2%) experienced surgical site infection; 4 (12.5%) surgical site infections were seen in patients undergoing incisional negative pressure wound therapy and 65 (29.3%) were seen in patients undergoing standard closure. Multiple logistic regression revealed 2 significant factors: diabetes mellitus increased the chance of surgical site infection (OR, 1.98; p < 0.05), and the use of incisional negative pressure wound therapy decreased the chance of surgical site infection (OR, 0.32; p < 0.05). Obesity was associated with a trend toward increasing surgical site infection (OR, 1.64; p = 0.10). LIMITATIONS: This study is limited by its retrospective nature and the high baseline prevalence of surgical site infection. CONCLUSIONS: Incisional negative pressure wound therapy appears to reduce surgical site infection in open colorectal surgery. Further study may be helpful to identify patient populations who would have the greatest benefit from this technique(see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A115).

Current status of surgical intervention for the management of rectal cancer.

Surgery for rectal cancer has advanced greatly over the past decade. Our knowledge of total mesorectal excision has led to improved oncologic outcomes. The concept of extralevator abdomino-perineal resection shows promise for reducing recurrence rates in tumors of the low rectum and anal canal. Once popular, local excision of rectal tumors has now been shown to have largely unacceptable recurrence rates. Minimally invasive techniques of laparoscopic and robotic surgery are technically feasible, and promise decreased complications in the future. Finally, new colonoscopic and endoscopic techniques offer alternatives for those unfit for surgery.

Effects of 2 adenosine antagonists, quercetin and caffeine, on vigilance and mood.

Quercetin, a phenolic flavonoid found in small quantities in some fruits and vegetables, is an adenosine receptor antagonist in vitro marketed as a dietary supplement for purported caffeine-like effects. A double-blind, placebo-controlled, between-subjects study was conducted to compare the behavioral effects of quercetin to a central adenosine receptor antagonist, caffeine. Fifty-seven volunteers received either 2000 mg of quercetin dihydrate (a dose estimated based on in vitro receptor binding to be equivalent in potency to 200 mg of caffeine), placebo, or 200 mg of caffeine. One hour later, a 45-minute visual vigilance task was administered. The Profile of Mood States questionnaire was completed before treatment and immediately after vigilance testing. On the vigilance task, caffeine increased the number of stimuli detected (P < 0.02) and decreased the reaction time (P = 0.001). Caffeine increased self-reported vigor and reduced fatigue and total mood disturbance Profile of Mood States scores compared with placebo. Quercetin did not significantly alter any parameter, but values were typically intermediate between caffeine and placebo on those tests affected by caffeine. Quercetin is unlikely to have any effects when consumed by humans in quantities present in the diet or in dietary supplements. Caffeine (200 mg) administration resulted in the expected effects on vigilance and mood.

Current evidence-based opinions in the management of adenocarcionoma of the rectum.

The management of rectal cancer has drastically evolved over the past two decades as a result of implementation of circular stapling devices and the introduction of neoadjuvant chemoradiation. In spite of current aggressive multimodality treatments, the recurrence rate remains unacceptably high and the expected 5-year survival in patients who develop recurrent disease is dismal. The management of rectal cancer must involve a multidisciplinary approach. An understanding of the biology of rectal tumours may allow for selection of patients who may have an aggressive phenotype allowing for alterations in the operative and neoadjuvant planning. Efforts to improve local control and survival in rectal cancer are the focus of multiple current clinical and preclinical research efforts. Preoperative chemoradiation for and surgical management of rectal cancer, including the laparoscopic approach are areas of dynamic progression. In the present report, we review the current evidence in the new strategies pertaining to the multimodality approach in the management of rectal cancer.

High-frequency percussive ventilation improves oxygenation in trauma patients with acute respiratory distress syndrome: a retrospective review.

BACKGROUND: High-frequency percussive ventilation (HFPV), a hybrid of conventional mechanical ventilation and high-frequency oscillatory ventilation, has been used to salvage patients with persistent hypoxemia on conventional mechanical ventilation. We hypothesized that oxygenation would improve in injured patients with severe hypoxemia who were converted to HFPV after initial management with conventional ventilation. METHODS: Chart review identified patients with acute respiratory distress syndrome (ARDS) managed with HFPV. Oxygenation parameters (oxygenation index, OI; Pao(2)/Fio(2) ratio, P/F) and mean airway pressures (mPaw) were recorded at baseline and at 1 to 4, 8 to 12, and 12 to 24 hours after initiation of HFPV. Values at baseline and each time point after conversion to HFPV were compared by using analysis of variance or Kruskal-Wallis tests. RESULTS: Twelve patients, over 24 months, were reviewed. Baseline measurements were OI: 42.2 +/- 33, P/F: 70 +/- 31, (median +/- interquartile range), and mPaw: 29 +/- 8 (mean +/- standard deviation) cm H(2)O. After initiation of HFPV, mPaw did not differ from baseline. There was an improvement in OI (P = .01) from baseline at 12 to 24 hours after initiation of HFPV and in P/F at 12 to 24 hours (P = .002) and 8 to 12 hours (P = .001) after initiation of HFPV. CONCLUSIONS: HFPV may improve oxygenation in patients with ARDS without a concomitant increase in mPaw. A randomized trial of HFPV versus conventional ventilation in trauma patients is needed.

Endovascular treatment of celiac and mesenteric arteries stenoses: applications and results.

PURPOSE: To evaluate the safety and assess the role of endovascular therapy in a variety of conditions related to celiac and mesenteric vascular occlusive disease. Patients and methods Our retrospective study population included 25 consecutive patients (mean age, 66 years), in whom 28 procedures were performed on 26 stenosed or occluded mesenteric vessels (superior mesenteric artery [SMA] or celiac artery [CA]). Indications included chronic mesenteric ischemia (21 patients), including 2 patients who underwent stenting prior to a planned operative repair of a juxtamesenteric AAA. Three liver transplantation patients underwent stenting of an associated CA stenosis. One patient with a splenorenal bypass underwent stenting on an associated CA stenosis. The technical and clinical success rates and the incidence of complications were determined. Follow-up parameters included maintained patency on duplex sonography and sustained clinical benefit. The need for additional interventions was noted. RESULTS: All procedures but one were technically successful (96%). Major complications occurred in three patients (one transient contrast-induced nephrotoxicity and two pseudoaneurysms). Immediate clinical success was achieved in 22 patients (88%). The three clinical failures included two patients with an excellent angiographic outcome, but with single-vessel moderate severity disease. Survival table analysis of delayed clinical outcome showed primary and primary-assisted clinical benefits at 11 months of 85% and 91%, respectively. Primary and primary-assisted stent patencies, as assessed by duplex sonography and/or angiography, at 6 months were both 92%. Angiographically documented restenosis occurred in three patients. Restenosis in two patients with CA stents was due to extrinsic compression, and it was without symptoms in one patient and was treated satisfactorily by restenting in the other patient. Restenosis in one patient with an SMA stent was successfully treated by restenting. CONCLUSIONS: Our experience suggests a potential role for endovascular therapy of celiac and mesenteric arterial occlusive disease in a variety of clinical scenarios, with a low incidence of complications and a high technical success rate.
